SHAW – the original and the best.（SHAW -原创和best。）

The general principle of operation of an aluminium oxide sensor, for the measurement of moisture in air and gases, is well documented but the actual construction of this type of sensor, which varies widely from manufacturer to manufacturer, is critical to the performance and reliability of systems in field operation.（用于测量空气和气体中的水分的氧化铝传感器的一般工作原理有很好的文件记录，但这种类型的传感器的实际构造因制造商而异，对现场操作中系统的性能和可靠性至关重要。）

When purchasing a SHAW dew point sensor, you are buying into over 60 years of proven technical experience. The aluminium oxide sensing technology, used to measure trace moisture in dry compressed air and process gases, is a great example of why you can always put your trust in Shaw Moisture Meters.（当您购买SHAW露点传感器时，您正在购买超过60年的成熟技术经验。氧化铝传感技术，用于测量干燥压缩空气和工艺气体中的微量水分，是一个很好的例子，为什么你总是可以把你的信任在邵氏湿度计。）

Good quality construction of the aluminium oxide sensor is critical to the performance and reliability of systems in the field. However, the construction varies from manufacturer to manufacturer. Shaw Moisture Meters employ tried, tested and trusted methods. Methods which involve layering and treating high quality components in order to control sensor speed, sensitivity and base capacity.（氧化铝传感器的高质量结构对现场系统的性能和可靠性至关重要。然而，构造因制造商而异。肖湿度计采用久经考验和值得信赖的方法。方法涉及分层和处理高质量的组件，以控制传感器的速度，灵敏度和基础容量）

Shaw Moisture Meters manufacture the sensor base layer with a high level of precision. This precision produces a stable, reliable and drift free sensor for trace moisture. Our continuous research and development has enabled the manufacture of uniform and water vapour specific pores, ensuring a rapid and predictable response.（SHAW湿度计制造的传感器基础层具有高水平的精度。这种精度产生稳定，可靠和无漂移的传感器痕量水分。我们不断的研究和开发已经能够制造均匀和水蒸气特定的孔隙，确保快速和可预测的响应。）

The overall measurement range covered by the dew point sensor is –100 °C to +20 °C (-148 °F to +68 °F) dew point, which corresponds to 0.001 ppm to 0.2 percent by volume.（露点传感器覆盖的整体测量范围为-100°C至+20°C(-148°F至+68°F)露点，对应于0.001 ppm至0.2%的体积。）
